Due to the geographical layout of its distribution area, Langeland Water Supply only used to read its consumers’ water meters once a year, making leaks next to impossible to detect. However, after having installed ultrasonic water meters and a mobile reading solution from Kamstrup, the water utility now gets a regular delivery of rich data about the consumption and its supply network. To enhance its leakage detection, Langeland Water Supply chose to set up DMAs – a decision which quickly paid off.
For two Mondays in a row during the summer of 2015, the water utility first read one of the district meters and then all the water meters in that area. A comparison of the readings revealed that approx. 350 m3 of water had been lost in that week. According to the water utility’s operations manager, this method proved both time-saving and cost-efficient as detecting such a leak would previously have required a significant amount of man hours and taken up to several months.
